Chapter 7: Introduction to Ad Hoc Wireless Networks
1. Definition
- An ad hoc wireless network consists of mobile nodes (hosts) connected by wireless links.
- The network topology (physical connectivity) changes randomly due to node mobility.
2. Challenges
- Traditional wired network routing protocols cannot be used due to:
- Dynamic topology
- Lack of centralized infrastructure (e.g., base stations or access points)
- Bandwidth constraints
- Resource (energy) constraints
3. Content Overview
- Issues in designing a routing protocol for ad hoc wireless networks
- Classifications of routing protocols
- Discussion of existing routing protocols with illustrations
Issues in Designing a Routing Protocol for Ad Hoc Wireless Networks
1. Mobility
- Problem: Network topology is highly dynamic due to node movement.
- Impact: Frequent path breaks during ongoing sessions.
- Requirement: Routing protocols must efficiently manage mobility.
- Comparison: Wired network protocols handle path breaks more slowly, making them unsuitable for ad hoc networks.
2. Bandwidth Constraint
